Question: QuickBooks crashes with error connection has been lost on my local machine. I feel this is a problem with the QuickBooks company file. How to fix it?
If you have already tried the QuickBooks Install Diagnostic Tool, the other method to fix the issue is running the Verify and Rebuild Data Utilities. These tools will help you verify if there are any data issues in your file that contribute to this issue.
Before doing so, make sure to create a backup copy to help avoid accidental loss in the future. Once done, let’s start with performing the troubleshooting steps.
To run the Rebuild Data utility:
- From the File menu, click on Utilities.
- Select Rebuild Data.
To run the Verify utility:
- From the File menu, click on Utilities.
- Select Verify Data.
If you get the same result, I suggest restoring the previous backup copy and run the Verify and Rebuild Data Utilities. Doing so will determine if the issue is with the company file or the software itself.
If the issue persists, I suggest contacting our Technical Support Team. They have extra tools, such as screen sharing, to dig deeper into the issue.
